The alcohols are firstlyoxidized either chemically or enzymatically to the corresponding aldehydes or ke- ---- tones, followed by aldol condensations using a catalyst to give the corresponding enals or enones. The enals or enones are subsequently GC and selectively hydrogenated using a recyclable heterogeneous metal catalyst, organocatalyst or an enzyme to provide linear or branched 1-1 © functionalized alkanes with an aldehyde, keto- or alcohol functionality. The process is also iterative and can be further extended by f'1 repeating the above integrated catalysis for producing long-chain functionalized alkanes from simple alcohols. C
